Djokovic inspired his country to victory back in 2010 and he's hoping to do so again this year but Serbia face a big stumbling block in the shape of the USA this weekend. Sam Querrey and John Isner spearhead their country's hopes and they've requested a super fast indoor court be laid to give them the best possible chance of serving their way past Djokovic and co.

The world number one knows he's in for a tough time. "USA is the most successful nation in this competition," Djokovic said. "They have a lot of good players. As you mentioned, Sam and John are the leaders of this team. And, of course, Bryan brothers which are the all-time best doubles pair. They are very strong. They have chosen these conditions because they believe it's going to go in their favour. They have a strong serve. With this altitude, it helps the serve more.

But we played in these conditions before. I played Sam and John, you know, in previous years few times. I know their styles of the game. This competition is very unique because you get to rely on the home support. So it's going to be quite different. Obviously we going to have an extra motivation to play and win for our country."

And although they're competing on foreign soil, Djokovic is hoping that Serbian ex-pats will come and provide them with more support to spur them on.

"In certain parts of America there's a big community of Serbians, like Chicago, for example," he explained. "I think there's a community of 300,000, 400,000 Serbians. It's not so far away. Hopefully they can manage and come and support us obviously if their time allows. We hope for that support because, as I said, in this competition it can be decisive, it can be crucial. You can't compare it to any other individual tournament really because you have the national captain sitting on your bench. Behind the court you have 10, 15 people from your team, your colleagues, supporting you every single point standing up. It really kind of awakens that patriotic energy inside of you that maybe you don't get to experience as often on the tour. That's why you get even extra motivated to perform your best and to bring a point to your country."
